FASTENER FOR DRIVING B ELTS OR STRAPS.

SPECIFICATION forming part of Letters Patent No. 656,757, dated August28, 1900.

Application filed May 29, 1900.

To all whom t may concern.'

Be it known that I, FRnDRrc EDWARD WHITHAM, a subject of the Queen ofGreat Britain, residing at Sowerby Bridge, in the county of York,England, have invented certain new and useful Improvements in Fastenersfor Driving Belts or Straps, of which the following is a specification.

The object of my invention is to construct a new or improved fastenerfor driving-belts of all kinds, so as to be cheap, durable, easily andquickly applied, and so effective that the greater the strain or tensionupon the belt the greater the grip of the fastener upon the ends ofsame. p

Figure lis a longitudinal section of myimproved fastener fordriving-belts and the like. Fig. 2 is a cross-section of my improvedfastener. Fig. 3 is a plan of my improvedfastener. Fig. iis alongitudinal section of my improved fastener, showing method offastening or securing the ends of driving straps or belts. Fig. 5 is aplan showing my improved kfastener applied to a driving-belt. Fig. 6 isa plan of a modification of my improved fastener when used for large ormain drivingbelts.

I construct my fastener of a suitable metal frame in the form of abuckle A, bent so as to conform to the periphery of the pulley or drumover which the belt B passes and having a cross-bar or midrib C in thecenter. Upon the top side of this cross-bar is a stud or projection D,and upon the under side two studs or projections E E. One end F of thebelt is passed underneath one end bar G of the fastener over thecross-bar C and underneath the other end bar I'I, the stud.D upon thetop side of this cross-bar C passingthrough a corresponding hole J inthe belt. The other end K of the belt B is passed through the fastenerin a similar manner, but over the end F of the belt already fixed. Asuitable buffer, cover, or packing L, of any suitable material,preferably of the same material as the driving-belt, is placed upon thetwo studs E E upon the under side of the cross-bar C, the top of whichbears against the under sideof the belt. A washer M is placed on eachstud E E and the ends riveted up, so securing said cover L in positionand presenting an even or regular surface to the face of the pulley.This fastener may be of any size and have one or more midribsorcross-bars. Also I preferably form the under sides of the end Serial No.18,365. (No model.)

bars G H and the top side of the cross-bar C fiat, so greatly improvingthe friction or resistance set up by the tension on the belt.

When applying my invention to large or main driving-belts, I prefer touse a fastener such as shown at Fig. 6, with a longitudinal midrib N, soas to strengthen the end bars G H, which are subject to great strain.Also I prefer to divide the ends of the belt B longitudinally, forming aslot P. This slot P allows the end to pass on each side of the mid.

rib N and be secured in the manner before described. By these means theends of the belts are effectively secured and an even and easy runningof the belt obtained. A further advantage of this invention is thatbesides permanently securing the ends of said drivingbelt, should suchbelt stretch and becometoo slack, the ends may be easily and quicklyreleased, the belt tightened as required, and again secured. Theoperation being eected by any unskilled workman, a great saving in time,labor, and expense is obtained.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination, with a curved frame provided with cross-bars at itsends and an intermediate cross-bar provided with upper and lower studs,of the end portions of a belt passing under the end cross-bars and overthe intermediate cross-bar and having holes which engage with the upperstud, and a coverplate secured to the lower stud with ,its end portionsbearing on the belt below the end cross-bars, substantially as setforth.

2. The combination, with a curved frame provided with a longitudinalmiddle bar, cross-bars at its ends, and an intermediate cross barprovided with upper and lower studs; of the end portions of a beltprovided with slots which engage with the said middley bar, said endportions being passed under the said end cross-bars and over theintermediate cross-bar and having holes which engage with the upperstuds, and a cover-plate secured to the lower studs with its endportions bearing on the belt below the end crossbars, substantially asset forth.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
